Atlas Copco High Air Pressure Drilling Hammer For Hard Rock Mining Down The Hole DTH Hammer


Describtion


In DTH hammers, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH hammers a nearly constant penetration rate regardless of hole length.


• Small to medium size drilling diameters
• Works in low pressure range, capable of drilling shallow to medium hole lengths

Advantages


dth hammer:dth hammer spare parts
More efficient energy transfer.Valveless air distribution. More reliable.
Faster drilling speed, 15%-30% higher than others.Simple design of the piston, long life
Lower air consumption and lower oil consumption. oil consumption is about 10% lower than othersFewer internal parts, simple structure, longer life, less failure and easier to maintain because all the parts are heat treated.
Direct factory priceEasy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.

Applications
